Novel artesunate–pyrimidine-based hybrids with anticancer potential against multidrug-resistant cancer cells
(Royal Society of Chemistry, 2023)
The synthesis of 17 hybrid molecules, consisting of artesunate, a derivative of naturally occurring artemisinin, and synthetic 4-aryl-2-aminopyrimidines, is described. New compounds were designed to improve the parent ...
Novel polyurethane network/organoclay nanocomposites: Microstructure and physicochemical properties
(Elsevier, 2022)
A series of novel polyurethane network/organoclay nanocomposites (PUN-NCs) with different soft segment contents (30–60 wt%) was prepared by in situ polymerization in solution and characterized. PU network (PUN) was made ...
Heavy metal concentrations in the soil near illegal landfills in the vicinity of agricultural areas—artificial neural network approach
(Springer Nature, 2023)
Purpose To anticipate the impact of illegal landfills, development of new models should become a part of environmental risk management strategies. One of such approaches includes applications of the artificial neural network ...
Pd Nanoparticles Supported on Ultrapure ZnO Nanopowders as Reusable Multipurpose Catalysts
(American Chemical Society (ACS), 2023)
Herein, we report the synthesis and application of a highly active andversatile Pd/chemical vapor synthesis-ZnO (Pd/CVS-ZnO) catalytic system. The twosteppreparation of the catalyst includes chemical vapor synthesis (CVS) ...
IIR Cascaded-Resonator-Based Complex Filter Banks
(MDPI, 2023)
The use of a filter bank of IIR filters for the spectral decomposition and analysis of signals has been popular for many years. As such, a new filter-bank resonator-based structure, representing an extremely hardware-efficient ...
Heterologous Expression and Partial Characterization of a Putative Opine Dehydrogenase from a Metagenomic Sequence of Desulfohalobium retbaense
(Wiley-VCH GmbH, 2023)
The aim of this research was to prove the function of the putative opine dehydrogenase from Desulfohalobium retbaense and to characterize the enzyme in terms of functional and kinetic parameters. A putative opine dehydrogenase ...
Immobilization of ArRMut11 omega-transaminase for increased operational stability and reusability in the synthesis of 3α-amino-5α-androstan-17β-ol
(Elsevier, 2022)
The aim of this research was to improve the operational stability and enable the reusability of ω-transaminase for synthesis of new enantiopure chiral amines of steroids. Dihydrotestosterone was used to optimize the synthetic ...
